To all alto In it my mam.

a citizen of the UnitedStat'esand resident, of Akron, Ohio,.hja vej invented new and use-f full inprovements in Gaskets, of which the following is a specification. N invention lat is te valve, and has in place an automatic valve 'of a. tyPeused d in-balloons, air ballonet's andthe 'like.

is an object ofiny inventionto provide a means for attaching an automaticgas or air valve tothe envelope of a'balloon, air" ballo'net;flor similargaseous fluid receptacle provided withja flexible wall; which means will facilitate the removal from or the in-j sertion of the valve into place. 3 p y It is a further object of my invention to provide a "gasket of such structuregthat, when attached to. the balloon "envelope the valve may be readily mounted therewithin and secured theretofwithout the necessity of manipulating a plurality of nuts or "the like.

Other objects and advantages will appear as the description proceeds, "and" the invention will 'be more particularly defined in the claims hereto a pended. y y

"Referring" to Figure lygthenumeral 10 designates, as afwhole, a'nfautomatic valve such as used on balloons or 'air ballonets, or

, thelike,"for inaintainingan equilibrium of pressure difference by coinpensating for any variations in atmospherlc pressure, such variations bemggcaused byfchange in altitude,

temperature and "other iatrn'ospheric conditions.

cles the flange 17 on the gasket. 13 andbinds the gasket to the'annulus 1 1. 'Whi1ea single band 16' has been shown,

l I have found that two 'bands" may be used with advantage? The split edges of the balloon fabric 14 are secured to the gasket 13 by cementing or particular reference to' a deyice'for se u ng i A has a bead 18 on its inner surface which. conforms to and fits within a recess in the annulus, and it has also a bead lilonits outer surface to preventthe clainpingring,

or band 1'6' from slipping offP'This gas 'ket 13, tapered toward itsouter edge asat' 13 m asto', form a better unionwithf-the envelopeyis 'reinforcedwitli fabric at 13 and i s'especially adapted for settinga gas valve like 10 in an envelopeyso" that not only'is a ti ght' joint "secured, but"; the valve may: be

readily and quickly inserted inplace andre- IHOVG ing"a'- knot in the end thereof, as shown; the cable being part oftli'e manual operating mechanism referred to below.

To the outer'ced'ge of the dome is" cured one section-23 of the gasket2'3,*which gasket forms "the subject matter-of my co- Thevalve-coniprisesa dome 20,; \vhi'ch is concave-convex in fo'rlnand is provided at its center with a lug 2101' 'thelike, to which a cord orcable 22 may be-fastenedby markpending application Ser.

Cooperating with thefpart or section 23 of the gasket isa secon'dpartorsection 23* secured to the annulus 11,:and 1. adapted 5 to contact with the section 23 aswillxbe apparent from Fig. 1.

Normally the valve 10 is automatically" operated by diflerence in pressure-between thatinside the envelope and that ofthe atmosphere to open the valve for the "relief of pressure inside the envelope. The mechanismfor effecting this operation consists of? the disk-like dome 20, above "described, which is exposed to atmospheric pressure on: one

'loo

side, and to that inside: the envelope on the;

other.

tral portion thereof andopposite the lug 21 a stem 30 which issupported*orreinforced by any suitable IHBELDSSHCh as a'icollar 31 carried by a concaved plate or disc82 secured to the dome, which gives the device greater rigidity. This strain '30" passes This dome has secured tothecenthrough a central frictionless bearing 33 supported bya hub 3-1 formedat the meet ing point ofthree spider arms 35 which are radially arranged, being fixed to the'inner surface of the annulus' ll at-their outer ends, and projecting inwardly to the center hub '34; A pair ofears 36 is formed integral with each spider arm 35 near the outer end thereof, and between the ears of each pair is pivoted a bell-crank lever 37 Helical contractile springs 38 are secured at one end to the. shorter ends 37? of the bell-crank 37, and the "otherfends" of .the springs 38 are fastenedlto arms 39 of toothed sectors 40fjpivotedfbetween other ears 41 carried bytlie'spider arms 35 at their inner ends and near the -,hub.3 i; QThe long arm 37? of each bell-crank 37 is connectedt'o lugs 42 secured to the dome 20, 'and near, the center thereof,

by an r links 43." jItfwill thus be seen a "that the springs 38' tend to move the Evalve toward clo'sedjposition by pullingthe dome 20 toward the envelope, bringingv the lip -portions only of the asketsections 23 and. i23'3 into contact to s ut ofl:' the outflow of gas.

In addition to the mechanism for auto matically operating the valve, 1- have pro- ,vided a 'manually operated means which is more fully-described and claimedin my cogenjding application Ser. No. 331,200, of even ate,of whichi'it forms the chief S bj matter. This manual operating mechanismis carriedby a, oke 60 spanningthe dome and having flaring legs or bifurcations, 61, thefends of-cwliich arenbolted by bolts GP, or otherwise-vsuitably secured to lugs 16 riveted or br'azed to the ring 16 and exten'd-v ing radially therefrom, said lugs 16 being spaced apart peripherally so, that the legs 61 span and contact with the outer surfaces thereof. This arrangement makes a rigid support for the yoke 60 and provides, moreover,--ameans whereby the ring 16 and-frame 60 can'beremoved as aunit, it being only necessary to loosen the turn-buckle 15 when the valve 10 r can, be withdrawn from the gasket 13. The valve can thus be freely removed without disengaging the ring 16 from a a A guard consisting of a conoidal case thermore be readily manufacturedbyjvulan annulus, said annulus being said annulus. l a 2. In combination with the envelope of the gasket 13,01 the frame 60 can be detached from the' ring by "merely removing the four bolts 61 Without disturbing the va vc;

ing,.perforated to re'duce weight, has been provided to protect the valve mechanism 10, and is secured to the annulus 11 by means of screws so as to enclose the valve 10.

It will thus be understood that I have provided a gasket 13 of. such shape that when cemented to the envelope of a balloon or air ballonet andgwithin an aperture" in y the same, a valve, suchasfllO maybe eas ly and quickly inserted ,within' the' gasket "and tightly secured by ,s'crewing'fup theflturn-l buckle 15, The insertion and removal.e'an
